Abstract
A test and measurement device includes an input port to receive an input signal, a sampling circuit structured to generate a sample from the input signal, in which generating the sample from the input signal produces an amount of kickout energy, and an energy reducing circuit coupled between the sampling circuit and one or more other components of the test and measurement device, the energy reducing circuit structured to decrease the amount of kickout energy from the sampling circuit. The energy reducing circuit may include or be combined with a pick-off circuit. Methods are also described.
Claims19
A test and measurement device, comprising:
- an input port to receive an input signal;
- a sampling circuit structured to generate a sample from the input signal, in which generating the sample from the input signal produces an amount of kickout energy;
- an energy reducing circuit coupled between the sampling circuit and one or more other components of the test and measurement device, the energy reducing circuit structured to decrease the amount of kickout energy from the sampling circuit and pass an energy-reduced input signal;
- and
- a clock recovery circuit configured to receive the energy-reduced input signal from the energy reducing circuit.
A method of operating a test and measurement device, comprising:
- receiving an input signal at an input port;
- generating a sample from the input signal, in which generating the sample from the input signal produces an amount of kickout energy;
- reducing the amount of kickout energy in an energy reducing circuit;
- picking off a signal from the energy reducing circuit;
- and
- sending the picked-off signal to one or more other components of the test and measurement device, the one or more other components comprising a clock recovery circuit configured to receive the picked-off signal from the energy reducing circuit.
